- GuestWhat are we looking at?
- Bugscope Teamhi meg, welcome to bugscope
- Bugscope Teamthese are tenent setae
- Bugscope Teamon a ladybug
- GuestHow is the instrument moving the sample around?
Bugscope Teamthe sample is still, not moving at all.
- Bugscope Teamwell, that's not true completely
- Bugscope Teamthe stage does move in the X and Y and Z
- GuestI have a group who will be on line on May 2. Will they be able to move the bug?
Bugscope Teamabsolutely, you will have controls to move around, change the magnification, focus and brightness. you also click on any preset and it will move to that preset
- 1:33 pm
- Bugscope Teami just gave you control, you should see controls on the right side now
- Bugscope Teambut we'll need to take control back soon, we are setting up presets for a class coming on in 30 minutes
- Bugscope Teamyou getting the hang of it? any questions?
- Bugscope Teamfocus can be tricky,
- Bugscope Teamat any time, you can click on a preset and it'll take you there
- GuestI'm impressed with what this does....is my computer slow?
Bugscope Teamdid you run the compatibility test yet?
- Bugscope Teamyou don't need a super fast computer at all. just broadband network
- 1:38 pm
- Bugscope Teamand there is some lag, that is totally normal. we are sending video through the internet to your browser, and that does have a little bit a lag
- Bugscope Teamyou just need to wait a second or so after each command you give the scope
- Bugscope Teamthere you go, nice focus
- Bugscope Teammeg, we need to take back control now, to continue presets
- Bugscope Teamyou are welcome to watch the session if you want, and ask questions
- Bugscope Teamyou can also login early to your session as well, or any other session before yours
- GuestThank you so very much!
- Bugscope Teamyou are welcome
- Bugscope Teamyou did great, but if you have any more questions please let us know
- Bugscope Teami see you haven't run the comat test yet, please do that before your session
- Bugscope Teamhttp://bugscope.beckman.illinois.edu/compatibity
- GuestI'm on a differant computer than the one which we'll be using so I have someone who will test it for me. Thanks
Bugscope Teamah yes, run the test from the computer(s) you will be using for the session
- Bugscope Teamyou'll need to enter in your password
- Bugscope Teamgood thinking meg
- GuestDo I need to enter the password to watch this session?
Bugscope Teamnope, as a guest you don't need a password at all
- Bugscope Teamyou only need your password when you run the compatibility test and for your session
- GuestI love what you do and hope we can get more schools involved.
Bugscope Teamthanks meg, we've been around for 11 years. this is bugscope 2.0, much better than the last version
- 1:43 pm
- Bugscope Teamyour students won't need the password, that is if your students are logging in separately.
- GuestIs Chas running the tool now?
- Bugscope Teamnope, cate (not logged in yet) is actually controlling the scope itself, gathering the presets
- Bugscope Teamonce we are done with presets, cate will login and then we'll wait for the teacher/students to login
- Bugscope Teamcate is a microscopist, so she is very good at finding cool/interesting places on the insects
- GuestI wrote about your outreach in the March 2010 Microscopy Today.
Bugscope Teamway cool!
- Bugscope Teamthank you!
- GuestWe'd like to get SEMs into more schools across the country.....
Bugscope Teamcool, but they cost a lot. that's part of the reason we did bugscope. students can control an ESEM as if it were in their school!
- Bugscope TeamDo you have a link to that MT article?
- 1:48 pm
- GuestSure....Microscopy Today is free online and you can call up the March issue.
- GuestThere are currently about11 schools actively using in-house SEMs. Volunteers and donors have made these possible.
Bugscope Teamwow, 11! that is great. i wouldn't have guessed that many
- Bugscope Teamhi mr. orton, welcome to bugscope
- Bugscope Teamwelcome welcome
- Bugscope Teamwe are setting up presets for your session
- Teacherstudents are logging in
- Studentyes we are
- StudentHow is everyone this afternoon?
- Bugscope Teamcool, welcome students!
- Bugscope Teamwelcome to bugscope
- StudentHelllo everyone\
- Studentthanks your the best alex
- StudentYeah, so what are we looking at exactly
Bugscope Teamthere are live images from an electron microscope, your teacher will be controlling it soon.
- Studenti have no lue
- Studentit looks like fins
- Bugscope Teamwe just have a couple more presets to get, then we'll start the session
- Bugscope Teamthese are buttefly scales
- 1:53 pm
- Studentokkay sounds goood alex
- Bugscope Teambutterflies have scales all over
- Bugscope Teamwe are not 100% sure it's a butterfly, but we are 90% sure
- Bugscope Teamit's not a moth
- Bugscope Teammoth's also have lots of scales
- Studenthow do you know the difference
- Studentoh... never mind
- Studentwhat is this?
- Studentwait, yeah how do you know the difference
Bugscope Teamwell, we work with entomologists and they are good at identifying insects
- Bugscope Teamthis is a cricket head
- Studentthat looks cool
- Studentwhy does this look gray
- Studentare the scales the same?
- Studentmr orton y dnt u say anything
- Studentthat looks creepy what is it?
- StudentHe doesnt know enough...
- Bugscope Teamthis is a spider claw
- Studentoooh kool
- StudentWhat kind of spider?
- Teacherit takes me longer because I care aboiut speling
Bugscope Teamthat's cool, no problem. i sometimes misspell things. no one is perfect
- Studenthow big are they?
- StudentI can really tell
- Bugscope TeamWE ARE READY!!!!
- Bugscope Teammr. orton, i just unlocked the session, you should see controls on the right side of the image now
- 1:58 pm
- Studentis that the same for humans?
- Bugscope Teamgo ahead and move around, if you get lost, just click on a preset and it'll move there
- Studentthats good to know
- Bugscope TeamThis is very cool -- I can't say I've seen a claw like this before
- Studenti don't know what i'm doing.
Bugscope TeamYour class is controlling an electron microscope. However, only one person can control at a time, right now it's Mr. Orton. We're here to answer questions and explain what you're seeing
- Studentme niether..lol
- Bugscope Teamthese are all live images from an electron microscope. it's black and white because there is no light used to get the image. it's all done with electrons
- Studentme ether
- Teacherlet's give control to gonzagaballer
Bugscope Teamthey have control
- Studentoh really
- Bugscope Teamgo ahead and ask any questions you have
- Studentthats a spider claw?
- Studentlooks like wings
- Bugscope Teamok! gonza, you've got control of the scope now
- Bugscope Teamthis is a very powerful electron microscope. you can change the mag on these insects up to 40,000x
- Studentkinda creepy though
- Studentlooks blurry
Bugscope Teamsure, things can be out of focus, but there is a control for changing the focus
- Bugscope Teamthe scope can mag much higher than that, but for these insects, 40,000x is about the highest to get a good image
- Studentwhat's that
- Studentis the hair coarse or fine?
- Bugscope TeamThe hair, setae, on spiders is often incredibly complex with intricate branching and patterns. More so than any other insects I've seen
- Studentyeah what is that
- Bugscope Teamthis is a ladybug palp
Bugscope Teamthese vacuum cleaner nozzle looking things are used to taste or manipulate food for the ladybug
- Bugscope TeamAnd especially around their spinnerets where the create the silk used for their webs
- Bugscope Teama palp is kind of like a tongue, it is used to taste food, but also to manipulate it
- 2:03 pm
- Bugscope TeamYes, palps are kind of like extra little hands for helping shovel food into your mouth, or to taste it
- Bugscope Teamnotice how the palp is near the mouth area
- Bugscope Teamthat palp can taste and smell food, and also help shovel food into the mouth
- Studentthat looks pretty weird
- Studentso kinda like tastbuds
Bugscope TeamExactly. We'd call the setae on them "chemosensory", because they give the insect chemical information
- Bugscope TeamThe swooping part going behind the palp is one of the two antennae
- Teachernice job gonzo
- StudentChas is confusing
- Bugscope Teamlike, if humans didn't such long hands, they wouldn't be able to eat so well, so we'd probably need palps, little things on the side of our heads that could shovel food into our mouths
- Bugscope TeamYeah, you're doing a great job driving
- Teacherlet's give control to DTMxPlatas
Bugscope Teamdone, DTM has control
- Studentrolly polly
- Studenti used to think these were cute?
Bugscope Teamscott, who isn't on right now says they look like mean librarians
- Studenthow bout a nose?
Bugscope Teamnope, no noses. insects have hair like things called setae. some setae are chemosensory and can smell things. palps also smell things, so do antennas
Bugscope TeamInsects don't have noses because they don't have lungs like we do. Instead of breathing through their mouth and into lungs like we do, insects have many smaller openings called "spiracles" through which air diffuses and provides oxygen directly to the body tissues. This is less efficient than using lungs to oxygenate blood that circulates to the organs, which is part of the reason why insects are limited in size
- Studentdo they have eyes
Bugscope Teamyep, compound eyes
- Studentwhats that mean?
Bugscope TeamCompound eyes differ from ours in that they're made up of many smaller facets -- each a functional primitive eye. Then their brains combine together all of the images from the primitive eyes to see the world around them, similar to how our brains merge the views from both our eyes
- Bugscope TeamYep. Rolly pollys, also called pill bugs, actually have gills on their underside which allows them to breath in moist environments
- Studentwhere are the eyes
Bugscope Teampreset #2 is a compound eye. ask DTM to click on preset #2
- 2:09 pm
- TeacherNice work Platas!
- Bugscope Teamcool!
- Bugscope Teamthis is a close-up of a compound eye
- Studentwhat is this
- Bugscope Teamthose bumps are called ommatidia, each one has a lens in it
- Studentthey have hairs?
Bugscope Teamyes they are short and stiff to help navigate through wind currents
- Studentthats the compound eye
- Studentwhat are the spikes
Bugscope Teamthose are called setae, and they are though to help the insect fly by sensing wind speed and direction
- Studentare they sharp?
Bugscope Teamthey are pretty sharp looking, but we wouldn't be able to feel them- they are too small
- Studentoh ok
- Studentwhat insect is this
Bugscope Teamclick on the scale bar in the lower left of the image, that'll tell you lots of cool info about the current image
- Studentwhat kind of spider is this
- Studentdoes spider hair grow just like humans?
Bugscope TeamI'm not sure. I don't know whether it continually grows and falls out like us or if it gets created once when the exoskeleton is formed
- Studenti don't like spiders , i'm scared.
Bugscope Teamsorry, it'll be okay though, the little critter is RIP
- Studentthis looks like an elephant
Bugscope Teamhaha it's a cricket and you can see its palps really well
- Studentnow what is this
- Studentthat helps a lot
- Studentwhat is this for
Bugscope Teamthis palp helps the cricket to taste and smell its food
- Studentwhy are they so ugly?
Bugscope Teamwell, they don't have mirrors that small so they have learned not to care about their looks.... :)
- 2:14 pm
- Studentwhats that?
- StudentSpiders get haircuts at the barber every two weeks
- Bugscope TeamThis is a haltere. It bounces back and forth during flight
- Studentwhats that hole thing
- Bugscope TeamA fruit fly
- Studentwhats it 4
- Bugscope TeamThe motion of the haltere is sensed by the fly and it helps the fly to fly in a straight line through the air even when there are gusts of wind
- Bugscope TeamIt works much like a gyroscope helps a plane navigate
- StudentI dont think Mr. Orton has a mirror either
- Studenthahaha muchoz funnyz
- Studentthat looks pretty cool
- TeacherShouldn't insult the man with the gradebook
Bugscope Teamha! good comeback mr. o!
- StudentWhy not, grade cant get any worse
- Teacherlet's give control to gibby
Bugscope Teamgo gibby
- Bugscope TeamHere you can very clearly see the array of round facets in the compound eye
- StudentLOL funny
- Bugscope Teamevery little circle is a small eye, called an ommatidium
- Studentthats alot of eyes!!!
- Student*potty break brb
- Bugscope Teamthe lenses in the compound eye are fixed, they can't move around like our lens can. so they have hundreds of lenses pointed in a curved area, that way they have good peripheral vision
- Studentcan we look at it a little closer
- Studentso theire eyes are more powerfull then ours
Bugscope Teamwell, our eyes have certain abilities theirs don't. i think our eyes work for us pretty well, and compound eyes work well for insects
Bugscope TeamOur eyes are very versatile, they have both near and far vision, but they require a lot of maintenence (eyelids, tears, muscles to move them, etc). Insect eyes are very low maintenance and simpler for their brains to process
- Studenthow many lenses do they have
Bugscope TeamSome have tens, some have hundreds. It tends to depend on how important their vision is for survival. Flying insects will have more than insects which live underground in the dark
- 2:19 pm
- Bugscope Teamthose are antennae hanging down from its head
- Studentwhat is this
- Studenti think it would be cool if we would have compound eyes to see what is like to look at things how they do
Bugscope Teami think if we suddenly had compound eyes we would be way creepy looking with these huge bulbous eyes
- Studenthow long do they live
- Bugscope Teamsome ants don't have any eyes at all, they use their chemosensory setae to follow chemical trails of their mates
- Studentthey dont?!
- Studentoh wow
- Studentwhy is their mouth in segments kinda
- Studentwhats their life span?
- Studenthow about if there sensory breaks
- Studenthow do they know where to drop
- Studentwhat is that???
- Studentthose are eggs dah
Bugscope TeamThey are called 'lamellate' antennae, from a June beetle like Alex said. They unfold when the beetle is smelling the air.
- Bugscope Teamthis is the end of an antenna on a june bug, i think
- Studentyea we would be ugly
Bugscope TeamSome people wearing those huge wrap-around sunglasses have already achieved the look
- Studentyeah i think we would look very weird
- Studentwhats their life span?
Bugscope Teamjune bugs live part of their lives as a larva, but once an adult, it'll like maybe a season, couple of months maybe?
- Studentsalt? thats not a bug
Bugscope Teamwe don't always have to look at salt. We sometimes put other interesting things in the scope for you to see
- Bugscope TeamHi all - sorry I'm a little late to your session! :)
- Studentits okkay Rob nice to have you!
- StudentLATE thats not good!!!!
- Teacherplease give control to Cheer16
- Studentlike sugar
Bugscope TeamWe were contracted by Domino sugar once to look at some of their products for them
- Bugscope TeamCheer16 is in control!
- Studenti agree with you Chas 2
- 2:24 pm
- Bugscope Team:)
- Bugscope Teammmmm, sugar...
- Studentthis looks like something from the ocean
- Studenti agree
- Bugscope TeamWe're looking at hairs on the bottom of an insect's foot, called tenant setae.
- Bugscope TeamThese help the insect hold onto smooth surfaces, like glass, or a smooth leaf surface.
- Studentit looks like a seaenemeny
- Studentdon't they get worn out from walking
Bugscope TeamYou can think of it kind of like a koosh ball - the setae compress and curve against the substrate, and I believe they are tipped with a little ball of oil.
- Studentwow thats cool
- Bugscope TeamThese tenant setae sometimes have pores which excrete a sticky substance to help them adhere to walls, window glass, ceilings, etc
- Bugscope TeamYes, what Chas said.
- Studentis this one burned
Bugscope Teamit looks like it is rotting or got covered in some liquid and the liquid dried. Not a very good specimen
- Studentyeah Chas
- Bugscope TeamGeckos have a similar pad of hairs, but they are 10-100x smaller and rely on a dry-adhesion property unique because of their small size
- Studentlooks like lint or something
- Bugscope TeamHm, I think this is the broken base of an antenna.
- Studentlooks like a pineapple
- Bugscope TeamYou can see a screw head!
- Studentis htat a star
- 2:29 pm
- Bugscope Teammake a wish!
- Bugscope Teamtry not to drive off the edge.
- Teacherplease give control to Liz
Bugscope Teamliz has control now, go liz!
- Bugscope Teamyou are controlling a $600,000 microscope so be careful!!! haha
- Studentwhy liz
Bugscope Teambecause liz is cool....
- Studentmy rims are worth that much
Bugscope TeamYeah but can't look at bugs close up with a set of 22"ers
- Studenti made my wish hopefully it will come true
- Studenthow do you know
- Studenti have a bugatti veyron
Bugscope Teampretty fast/expensive car...
Bugscope TeamLook up the bugatti veyron national geographic special on youtube, it's fascinating and scientifically interesting to boot!
- Studentlol jk
- Studenti don't think liz can handle the controls
- Studenti agree with cesar21
- Studenttrue true
- Bugscope Teamliz, you are doing great!
- Bugscope Teamgood work, focus the other way if the first way doesn't work
- Studentare you sure alex
- Studentits hard to control the scope
- Studentthanks a lot but i have to run to another class! thanks admins
- Bugscope Teamyou all did great, good work
- Student THANKS!!!!:)
- Bugscope Teamyou are welcome
- Studenthey dont be hating no liz
- Bugscope TeamGreat job guys, it was great to have you on
- Studentnow what is this??
Bugscope TeamA fly to the left, and the round things are impressions/bubbles in the carbon tape used to stick the bugs down
- 2:34 pm
- Teachersome have to go, but some can stay if that is alright
Bugscope Teamthat is totally fine, you've got the scope until 3PM central, another 30 minutes
- Studenti'm not hating liz i'm hating elizabeth
- Studentits a les16
- Studenthey thats my sister ima tell her jst watch
- Bugscope TeamThis is a great close-up of a fly mouth (at the top) and the eye (at the bottom)!
- Bugscope Teamnotice all the setae (hairs), you'll see a lot of that on insects...
- Studentthanks Chas 2 thats good to know
- Bugscope Teamthe setae function as sensory organs, in that they feel the environment with those setae
- Studentwhy are u so serious les16
- Bugscope Teaminsects have a hard outer shell called an exoskeleton, and it can't feel anything. so those setae stick through the exoskeleton and connect to nerves underneath, and that's how it feels things
- Studentthats blurry
- Bugscope Teamclick again to stop moving liz
- Teacherplease let Les 16 have control
- Teacherbuckle up!
- Bugscope Teamthere ya go, good work liz!
- Studentits pretty cool how were able to see all those small things that the insects have
Bugscope Teamright on!
- Studentis it to late to get off
- Studentclick or ticket
Bugscope TeamIt doesn't rhyme unless you say 'click it or ticket'
- Studentclick it*
- Bugscope Teamgo ahead and click on a preset les16, it'll take you there
- Bugscope Teamd'oh
- 2:39 pm
- Bugscope Teamany problems les16?
- Bugscope Teamcan we help?
- Studenti got it now thanks
- Bugscope TeamWe're off in the middle between bugs. If you choose a preset from the lower right it'll get you started going from an interesting spot
- Studenti don't think she knows what shes doing
- Studentwhat is this??
Bugscope Teamthat looks like a piece of juju- something that isn't part of the bug like dust or dirt
Bugscope TeamIt's hard to say this close. I think it's a bit of crud stuck on a spider's fang.
- Studentshe needs more practice
- Studentwhat is on the fang
- 2:44 pm
- Studentso the fang isnt smooth
Bugscope TeamNo, the ribbing may be there to reduce friction and help it slide into the victim more easily
- Bugscope TeamThere's the whole fang - you can see the pore at the very tip where venom flows into a bite!
- Studentsmooth as the rockies
- Teachersmooth to us but not to an electron
Bugscope Teamexactly, or maybe not to an insect
- Studentis that hole used to extract blood
Bugscope TeamNo, the spider will drink that through a mouth, which is between the fangs.
- Studentthats cool are all fangs like that
Bugscope TeamI am not sure, but any spider that makes venom has to inject it from somewhere.
- Teachernice job les
- TeacherPLease gice control to cesar
- StudentGot to run...thanks for everything Admins!
- Bugscope TeamNo problem!
- Bugscope Teamcesar, you've got control of the senate and the kingdom... i mean, the scope.
- Studentwhat is htat on the top
- Bugscope Teamthese bumps are the sticky tape that we stick the bugs to
- 2:49 pm
- Bugscope Teamit keeps the bugs still
- Studentoh thats cool
- StudentWhat is this
- Bugscope TeamThis is a scarab beetle. You can tell because the antennae look like those little combs (they're called 'lamellate').
- Studentdo their joints have something soft so the bones dont wear out
Bugscope TeamActually, yes. Insect joints are coated in a rubbery protein called 'resilin', which helps them move smoothly and conserves a lot of kinetic energy.
- Bugscope Teamthis is a june bug head
- Studenti mean exoskeleton
- Studentoh thanks bob i mean rob jk lol
- Bugscope Teamjune bugs are like beetls
- Bugscope Teamwell, they are beetles, a genus of scarab beetles
- Studentthats good to know
- Bugscope TeamYou can often times see complex patterns of setae or ribbing of the exoskeleton in or around the joints which I presume also helps reduce friction
- Studentoh ok thanks
- Studentoh i see
- Studentwhat is that black hole
Bugscope TeamLooks like where they were mounted with a pin previously
- 2:55 pm
- Studenthow does their mouth work
Bugscope Teamthe mouths of chewing insects work side to side, compared to our mouths. and those of insects seem much more complicated. We don't have palps to help us eat and taste food, either. Of course.
Bugscope TeamOne of the insects on here, the 'true bug,' has a straw instead of jaws. It sticks it inside plant stems or seeds and drinks the juices.
- Studentcan we take a look at the bottom???
Bugscope Teamyou mean the underside, which is actually the dorsal surface?
- Teacherabout 3 minutes left
- Bugscope Teamhere you can see those lamellated antennae
- Bugscope Teamwe usually mount insects on their backs so that we see the ventral side, where almost everything is happening
- Teacherthanks alot for all your help today
- Bugscope Teamthis is the tip of the abdomen
- Bugscope TeamThank You!
- TeacherWe need to get going guys
- Bugscope Teamthanks for using bugscope today. Feel free to sign up again in the future!
- Bugscope Teamyour class was great
- Bugscope Teamoops flexible
- Bugscope TeamThanks for the questions!
- 3:00 pm
- Studentthanks for the stuuf htat you thought us
- Bugscope Teamyou are welcome les 16
- Bugscope Teamgood work!
- Bugscope Teammr. orton, remember, all the chat and images are saved to your member page...
- Studentok thanks ofr letting us use it
- TeacherWe'll be back
- Bugscope Teamhttp://bugscope.beckman.illinois.edu/members/2010-018
- Studentbye and thanks a lot
- Bugscope Teamheh sounds great, thanks
- Bugscope Teamover and out...
- TeacherHave a great day
- Bugscope Teambye mr orton
